WATER strrLL.

Appl'ia'foa fi'l'a M'y 1o, 192o, serial No. 330,216. Rnewed October e, 1924.

This invention relates to a water still.

Anobject of the invention is to provide an apparatus of the class mentioned so constfructed as to aford an linusually large condensing area` whbreby the capacity of the app'aratus as a Water still is especially lar e.

A further object of the invention is the p ovis'ion of a. uniqne type of condenser with which either running water or still Water cool-body of Water is maintained in contact with the condenser walls.

he invention has as another object the pro'vision of means for automatically feedna,

' distilling chambe'r, Whereby the water withinI the distilling` Chamber is always maintained at a proper level.

In the' drawing's': Figure 1` is a' view in perspective o'f the apparatus, With' a frag'inent broken out of one side to show the details of the interior construction.v

igure 2 is tudinally,

Figure 3 is a transverse section on the line 3-3 of igure 2,V and Figure 4 is a perspective view similar to Figure 1, but With the cover removed. The invention, as herein shown, comprises a substantiall a vertical section taken longiy rectangular receptacI-e A having the bottom 1,' end walls 2 and 37 and the Sides 4 and 5. The upper e'dges of the ends 2 and 3 and the side Walls 4 and 5 are beaded as shown at Near the bottom of the end walls' 2 and 3 and side Walls 4 and 5 and sloping toward the end wall 2 is located a trough 7 which as an exterior flange 8 secured to the Walls o theV receptacle A' by Welding or the like d an interior flange 9 Which forms' the' bo'unda'ry of a central rectangular opening` for a perforate o r grated nieniber 11 having supporting legs 140 and which is adapted to supportjars or the like containing preserves When the device is being used as a steam cooker. EXtending from wall 4 to wall 5 and spaced above the fiange 9 of the troug'h 7, are two rods 12 hinged at one end as at 12"- and resting in cups 12a at the other end and which constitutesupports for a grate-like or perforate member 13 l I U be used for supporting preserve jars or the like in using the receptacle A as a steam coolrer. A condenser Bhaving the shell 14- of the receptacle A and fits o ver the -bead (3, thus forming a tight joint While at the same time permitting the condenser B to be easily removed. A fiange 18 is also provided at the top of the i along each end thereof from side to side.

are positione'd over distilled or condens'ed water accumulating on the Walls 19, 20, and 21 will run toward the edges 23 and be precipitated in the trough 7. VVithin'the bottom of the condenser B `and lyi'ng in the V- shaped passag'e formed bv the peculiar configuration of the bottom is a pipe 24 Which is perforated throughout its length and has an end piece 25 provided With a reduced portion 26 spaced from the Wall of the condenscr B Afor the attachm-ent of a suitable pipe for conveying water to the condenser. The end of the pipe 24 may be closed simply by a removable means such as a plug' or the like so as to afford easv access to the interior of the pipe for Cleaning.

An outlet Valve 27 is provided adjacent the top of the condenser B and I i closed .by a suitable screw cap 28 if desired.

edges 23 of the c'ondenser the trou'gh 7 so that 30 is secured to the receptacle A approximate the lowest level of th'e trough he top of the con'denser B is closed by a cover C which has the upstanding portion 31 carrying handles 32 at each end thereof and aifording and having the dependiug fits down over the Viiange 18 tlange Which and has a semicircular recess indicated by the numeral 33' for the out-let valve 27 so that such cover (l may be fitted onto the still foi` shipment, or may fit over the bead ti of the receptacle A, thus forming a Cover for either the condenser Bfior the..i;eceptacle A, but inrusing the device as a still'the cover C is never applied as it is desired to utilize the cooling influence of the atmosphere. V V

rfhe cover C is provided'vvith a 'lead Vor other suitable lining 31' to add Weight inorder to maintain contact of the cover flanige when the device is used asa steam cocker` also a hole 31a is provided as a steam escape passag'e for the Valve spindle to be later' described. A Water regulating valve for the distilling compartment is indirated at D and consists'of a tube 34 fastened as at 35 by Welding or the like in the `apex of the Walls 21. rl lhis tube is formed With openings 36 ben'eath the ridge 22 and with openings 37 adjacent the top. Fitting over this tube D at its upper end is a cap 38 having opening-s 39forV registration With the openings 37 in. the tube 34. This cap is held in place by. a pin 40 engaging in a groove or slot* 41. lVithin the tube 34 and above the ridge-22 tis' located a tubular Valve seat 42 Which has' a .eoncave upper end 43 and a tapered passage 44 which receives a tapered Valve body 45 carried by a shan'k 46 connected With a float 47 resting at the, water level Within) the receptacle A. A pin 48 extends from the upper end of the valve lbody 45 and projects through the capl38 for guiding the Valve. The operation of'the Valve isV as follovvs;v Water flows into the v-alve tube 34 through the openings .37 and is trapped above the valvesseat 42 When the valve body`34 israiscd to the closed position a the tube. 34.

by the rise of the float 47'. downvvard movement of the float 47 the valve bodym'oves away from the sleeve 42 Wit-h the result that 'water from the con- However, on the deiiser D flows past the valve body and through the tube 34 and the outlets 36 and into the lou'erportion of the receptacle A. f

lt Will be seen that the rate of vflow` may be 'regulated by turningthe partly or wholly uucover. the openiugs It will beobserved that the condenser ll) may be entirely removed in orderto use the receptacle A as a steam cjoolrer and in the zfcaseof such use the capior ciov-crV O may be fitted down over the head 6 to provide a tight closure. In the case of such use the valvebody 45 and the float 47 are also removed. A

In constructingthis device the component parts thereof are preferably formed of some lightl material such as aluminumin order to make the device .as light as possible for its cap 38 to only Leeasov size7 although it. is evident thaiit mav he equally Well formed of any other material suitable for the purpose.
